    • Elongated electrically nonconducting transducer preforms are made from a ff resin. The preforms have grooves in their upper and lower surfaces. Transducer elements may be formed from stacked preforms whereby grooves in their upper and lower surfaces form compartments between adjoining stacked preforms. PZT rods are disposed in the grooves disposed on the upper surface of each stacked preform, and a soft resin surrrounds the rods and fills the compartment. The method for making the transducer assembly includes the steps of loading by gravity the rods into the upper grooves of the preforms; stacking the loaded preforms so that upper grooves in the lower preform communicate with lower grooves in the upper preform, thus forming cavities; flowing a soft resin around the rods; and curing the soft resin.
    • 细长的非导电传感器预制件由刚性树脂制成。 预制件在其上表面和下表面具有凹槽。 传感器元件可以由堆叠的预成型件形成,由此其上表面和下表面中的凹槽形成相邻堆叠的预制件之间的隔室。 PZT棒设置在设置在每个层叠的预制件的上表面上的凹槽中,并且软树脂覆盖杆并填充隔室。 用于制造换能器组件的方法包括以下步骤:通过重力将杆装载到预成型件的上槽中; 堆叠加载的预成型件,使得下预制件中的上槽与上预制件中的下槽连通,从而形成空腔; 将软树脂绕在杆上; 并固化软树脂。

    • A transducer includes a rigid resin in the form of a solid block; a pluray of spaced and parallel piezoelectric rods of equal length disposed in the rigid resin and extending at one end thereof beyond the rigid resin; a solid soft resin enveloping the rods; and electrically conducting cover plates disposed against extremities of the rods; the rigid resin block being composed of a plurality of stacked preforms having spaced and parallel upper grooves wherein the rods are disposed. The process for making transducers with extended piezoelectric rods includes the steps of loading the rods into a plurality of spaced and parallel upper grooves of preforms made from a rigid resin; stacking the loaded preforms one on top of another to the desired height, the rods being flush with the preforms at one end and extending beyond the preforms at the other end; infiltrating a soft resin around the rods; curing the soft resin to a solid, compressible state; and applying electrically conducting cover plates against the rod ends.

    • A method, an apparatus and a recording medium are provided for communicating message payload data, especially noncontiguous message data, from a first node of a network to a second node of the network in response to a request to transmit a message. Such method includes dividing the length of a data payload to be transmitted into a plurality of submessage payload lengths, i.e., into at least a first submessage payload length and a second submessage payload length. Then, a first ordered submessage is transmitted from the first node for delivery to the second node, the first ordered submessage having the first submessage payload length. A first state of an environment is then determined in the first node as if the step of transmitting the first ordered submessage were already completed. Without having to complete the step of transmitting the first ordered submessage, a second ordered submessage is then transmitted from the first node for delivery to the second node, the second submessage having the second submessage payload length, the second submessage being transmitted in a way that takes into account the first state of the environment in the first node.
    • 提供了一种方法,装置和记录介质,用于响应于发送消息的请求,将消息有效载荷数据,尤其是不连续消息数据从网络的第一节点传送到网络的第二节点。 这种方法包括将待传输的数据有效载荷的长度划分成多个子消息有效载荷长度,即至少是第一子消息有效负载长度和第二子消息有效载荷长度。 然后,从第一节点发送第一有序子消息以传送到第二节点,第一有序子消息具有第一消息有效载荷长度。 然后在第一节点中确定环境的第一状态,就好像传送第一个有序子消息的步骤已经完成。 而不必完成发送第一有序子消息的步骤,然后从第一节点发送第二有序子消息以便传送到第二节点,第二子消息具有第二消息有效负载长度,第二子消息以如下方式发送: 考虑到第一个节点的环境的第一个状态。
